Burned-on sand and scale are removed to improved the surface appearance of the casting. Excess metal, in the form of fins, wires, parting line fins, and gates, is removed. Inspection of the casting for defects and general quality Metal Casting Inspection Methods | Casting Quality StandardsIn accordance with the investment cast industry standards, specific industry regulations, and/or the customers specified quality instructions, visual inspection is required to ensure genuine casting quality from start to finish. In terms of casting quality this means that we make sure parts are properly filled with metal (no cracking, tearing, holes or voids, non-fill, etc.). Our casting quality control experts also meticuVariance in cast dimension(s) is an inherent part of the manufacturing process. Due to these differences, it can be difficult to expect exacting dimensions throughout the production lot. These discrepancies in casting quality can be caused by the heat and hydraulic pressure of molten metal being poured into the ceramic mold, which can cause the metal to contract (move) as it cools or after post-cast heat treatment. The toolmaker compensates for these expansions and contractions when designing the mold.
